Description
Technical field
The present invention relates to touch liquid crystal display technique field, particularly relate to a kind of narrow circuit line-spacing multi-point touch liquid crystal indicator and manufacture craft thereof.
Background technology
At present, the application of touch liquid crystal display technique is more and more extensive, one of existing technical scheme is exactly in-cell technology, as shown in Figure 1, it is the method be embedded into by touch panel function layer (sensor) in liquid crystal pixel, be specially: first utilize ITO coating technique in the inside surface plating ito film of crystal liquid substrate 1, gold-tinted processing procedure is utilized to succeed ergosphere 2, and then with Double-face adhesive rubber alloy belt (OCA adhesive tape) 4 by cover plate 3(coverlens) and be bonded together with the crystal liquid substrate 1 of functional layer 2.Meanwhile, specialized equipment is utilized to be pressed together between cover plate 3 and crystal liquid substrate 1 by FPC (FPC) 5.The live width line-spacing of the functional layer pattern that this technical scheme is formed is smaller, and generally can only accomplish 30-50um, the touch function in this technical scheme is only to realize single-point touch and gesture.One of shortcoming of in-cell technology is exactly that yields is difficult to control, and this solution technique difficulty is large, poor operability, and cause product qualified rate low, yields is lower; Two of the shortcoming of in-cell technology easily occurs signal disturbing, also needs to be equipped with special IC; The shortcoming that in-cell technology is maximum or scrap cost is high, because in-cell adopts trinity technology in process of production, namely when producing, glassy layer, functional layer and liquid crystal layer generate simultaneously, as long as so wherein one deck goes wrong, all the other are two-layer even more multi-layeredly all can come into the picture, and scraps simultaneously; Add the touch-screen that produces with it and LCDs is integrated, the whole touch display screen of mobile phone finally will be caused to scrap.The live width line-spacing of the functional layer pattern formed is narrow, and can only realize single-point touch and gesture, and reason is that it comprises an one functional layer, which limits the quantity and width that form pattern lines, affects the performance boost of touch-screen.
Two of existing technical scheme is exactly caterpillar technique, and main technical schemes is: first utilize coating technique on crystal liquid substrate, plate one deck ito film, utilizes gold-tinted processing procedure to succeed ergosphere; Be bonded together with the liquid crystal of functional layer and cover plate with OCA adhesive tape again; Meanwhile, specialized equipment is utilized to be pressed together on by FPC between upper and lower functional layer, the live width line-spacing of the pattern of the functional layer of this technical scheme can only accomplish 30-50um equally, its touch function is also only to realize single-point touch and gesture, and its shortcoming existed equally is: (1) yields is difficult to control; (2) easily the phenomenons such as irregular colour are produced when using; (3) shortcoming that this technology is maximum is also that scrap cost is high.Because on-cell adopts trinity technology in process of production, namely when producing, glassy layer, functional layer generate simultaneously, as long as so wherein one deck go wrong, all the other one decks are even more multi-layered all can come into the picture, and scraps simultaneously; Add the touch-screen that produces with it and LCDs is integrated, the whole touch display screen of mobile phone finally will be caused to scrap.(4) on-cell technology allows production efficiency reduction, production capacity decline equally.(5) live width line-spacing is narrow, and can only realize single-point touch and gesture.It equally only comprises an one functional layer, which limits the quantity and width that form pattern lines, affects the performance boost of touch-screen.
